3. 2. Principles and Models of Solid Fuel Combustion

   Författare :Henrik Thunman; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; single particle; modelling; fluidized bed; thermochemical conversion; fixed bed; coal; thermal conductivity; fuel loading; measurements; thermochemical properties; biofuels; combustion; grate;

   Sammanfattning : Combustion of solid fuels stands for a substantial part of the heat and power production in the world. In this thesis different aspects related to the thermochemical conversion of solid fuels in fluidized and fixed beds are treated, such as: the combustion temperature of a fuel particle related to the surrounding temperature in a fluidized bed combustor (FBC); the fuel loading in a FBC; a transient description of the conversion of non-spherical fuel particles; the thermochemical properties and composition of volatiles released from wood; the thermal conductivity of wood during different stages of conversion; the modelling of a grate furnace; the general combustion behaviour of a fixed bed on a reciprocating or a travelling grate; and finally, the design and construction of experimental units for investigation of combustion in a fixed bed.

4. 3. Modelling and Experimental Investigations on Thermal Radiation in Combustion Environments

   Författare :Henrik Hofgren; Värmeöverföring; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal radiation; Property model; SNB; WSGG; LBL; Planck; particle; fly-ash; soot; grate; furnace; combustion;

   Sammanfattning : Thermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. LÄS MER
